摘要：
In this paper, we propose an optimized schedule called IRMP (Improved Row Message Passing) schedule, based on analysis of the existing message passing schedules. This type of schedule has changed the message updating order between variable and check nodes. In accordance with this schedule, an improved BP-Based decoding algorithm is proposed. Simulations show that, this algorithm has beaten the performance of BP-Based algorithms available in terms of error rate and number of iteration.
